Hey Portugal friends next week there will be Lots of Nuptial Flights every where In the following cyties, be sure to go out hunt and be sure you have where to put them after the catch. The ants will fly at morning after next days rains, I recommend you to take a walk and try to find wind colonies and map them before the rain, and if you are able, bring home some species workers and take very good pictures of :

Head - Side and Front point of View;

Torax - Side and Top View;

Petiole/s - Side View;

Gaster - Side and Top View;

And make sure you ID the ants. You can log in at Antweb.org and from the Link get all your country species:

When you got the list and You have open the images link you can now google imgs by the names and try to find out by yourself what species does the ant look alike, take a good look at Head, Torax Petiole/s and Gaster and find names and bring to us here at AC forum your guess and we will confirm for you (show us pictures). Don't forget to tell us the place so we can visit too xD.

Go back to the wild nest with awareness and be sure to find pats and look around corners and stones remember to don't catch them too close to the nest because they might be leaving or going for it to copulate. If you choose to caught them at the nest remember to mix males and queen alates from different nests of the same species (not recommended, this way they may copulate but not for sure and you wont be successful). If you did the map you can trace the path between same species colonies and be on those tracks because thats where you gonna find the most Queens.
